Bioacoustics of Tamasa caverna

Redescription of adult ( Figs 11 , 21 , 37 , 57 ). The species is described in detail by Moulds & Olive (2014) . Length of forewing 32–36 mm . Distinguishing features. Clearly differs in the male theca (requires dissection) ( Fig. 57 ). Distinguished from most Tamasa species by its larger size (forewing 32–36 mm ), and in having the head about as wide as lateral margins of pronotal collar. In these features it is similar to T. gigas sp. nov. but differs in its smaller size (forewing less than 37 mm ) and the males in having four long timbal ribs instead of five, plus tergite 3 is brown laterally instead of black. It is the only Tamasa species found among the boulders of Black Mountain. Song. The song is described together with an oscillogram by Moulds & Olive (2014) . Males rest and sing from within caverns between boulders, usually clinging to the undersides of boulders.
